Introduction
When we go to build our computers one of the things I have heard is to always get an i7 for gaming but there's lots of us out there that don't have a lot of money to invest into an i7 or even for that matter a hexa-core i7. While i7 CPUs will last longer for gaming it's not really necessary considering that an i7 is more centered around server and productivity workloads rather than gaming itself. Granted with an i7 you could run more than 1 game but majority of people focus on one game and maybe idle in the main meun of another. For example, When I'm waiting for my friends to join me and play Rainbow Six Siege I load up something else like Lego Worlds to pass the time if it will take them a while to get done with their Ranked match. To idle in a main meun will not take up as much of your CPU horsepower than if you were actually in-game itself with the map loaded and lots of action going on around you.
Benchmarks
I see a lot of people with this kind of mentality that benchmarks are the end all, be all but I stress that benchmarks don't really matter much other than for bragging rights or stress testing your computer because benchmarks don't give you a really great picture of real-time performance of your hardware, It just tells you what it will be like while under maximum load, it doesn't really paint a picture of what you can expect with your specific piece of hardware and every piece of hardware is unique in the type of performance one can expect to get.
Some people will get a processor (CPU) that can overclock up to 5 GHZ, Others might only just be able to overclock and get 4.6 GHZ so it's all a matter of luck. Don't go on other blogs or computer review sites to see performance benchmarks and realistically expect that kind of performance in your specific computer. The only way you can be sure that you get that level of performance is if you buy your Processor on Ebay and see in the listing that somebody posted a picture of CPU-Z software with that specific clock speed. However doing so can be a gamble because it doesn't guarantee that the hardware itself will last and also the warranty might not apply on it if the manufacturer itself has a clause that states the warranty is invalid if you transfer ownership of the hardware itself if somebody registered it either electronically or manually on the manufacturer's site.
